I'm currently using FME to validate geometries, coming from 3rd parties, making sure there to OGC Standards.
I was hoping to be able to replicate these checks in QGIS, but find the tools available (Check Geometries Plugin, Topology Checker and Check Validity) do not currently flag the issues to the same degree as FME. We need a way these 3rd Party's can check the geometries and find the issues, before sending them onto us, but preferably through QGIS.
Currently, FME is flagging an issue
Hole Outside of Shell. Indeed, when I check the datasets with the issue and show/label the vertices it shows the problem
Is anyone aware of a more rigorous tool/plugin preferably open source, which can be used to check validity of Geometries to OGC standards? Or alternatively, does anyone have a way I can do this in QGIS?

Typical though, the extracted WKT doesn't have the issue, the geometry string exceeds the character limit for the post, so I had to clip it, evidently in clipping it, and converting it to WKT, the issue was addressed...
